To solve this equation, we have to use the distributive property to multiply 5y through the parentheses.
-45y - 15y^2 = 13
-15y^2 - 45y - 13 = 0
15y^2-45y-13=0

The answer is 12cm because area (420) divided bye height (35) gives you the corresponding side 12cm.
7.3 ------ 8.1 8.5 8.9
let us try to find the common difference here using last three terms
8.5-8.1=0.4
8.9-8.5=0.4
so it is clear that common difference is 0.4
so adding 0.4 to 7.3 will give the next term
7.3+0.4=7.7
Answer : missing number is 7.7
